Improvement in grain-tollers



UNITED STATES PATENT Ormeac HENRY E. DOUGLASS, OF NEW BRIGHTON,PENNSYLVANIA.

IMPROVEMENT IN GRAIN-TOLLERS.

Specification forming part of Letters Patent No. 223,034, dated December30, 1879 application filed October 2, 1879.

To all whom 'it may concern:

y Beit known that I, HENRY E. DOUGLAss, of New Brighton, in the countyof Beaver and State of Pennsylvania, have invented certain new anduseful Improvements in Devices for Telling Grain 5 and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to Which itpertains to make and use it, reference being had to the accomv panyin gdrawin gs,vvhich form part of this specitcation.

My invention relates to an improvement in devices for automaticallytolling grain, or separating from the bulk of grain a certain portion,as is customary at mills, in payment for the grinding; and it consistsin a rotary hopper provided with a spout, from which, when rotating, arequired fractional quantity of grain falls at every revolution into astationary compartment proportioned to the quantity of grain to be takenoft', while the remaining portion falls into other compartments and isseparated from the former, as vill be fully described hereinafter.

The accompanying dra-Wings represent my invention.

Figure lis a vertical section of my invention. Fig. 2 is a plan view ofthe same.

In the frame A is supported an open cylinder, B, the closed bottom ofwhich is cut obliquely. Within the cylinder is a circular horizontalframe, O, resembling a Wheel, its diameter being that of the inside ofthe cylinder. Instead of having spokes at regular intervals, like aWheel, the circular frame is divided into compartments D, of unequaldime11sions,\vl ich compartments bear certain relations to the surfaceof the frame C. If, for instance, the surface of one compartmentoccupies one-seventh part of the Whole surface ofthe frame, theremaining part Would be six-sevenths, (-25) and, when rotating, theone-seventh of the grain falling from the spenta would enter thecompartment of that size, While the remainder drops into the others. y l

The frame O being open, the grain passes freely through it to theinclined bottom, at the lowest part of which is an opening, a', fromwhich it may be led to any convenient place.

Attached to the inside of the cylinder, under and in contact with theframe O, is a spout, E, of the form of the compartments D, which spoutpasses through the slanting bottom of the cylinder; hence all the graindropped into any one of the compartments placed over this spout becomesseparated from the rest.

The frame O, being movable, may be so adjusted that either one of thevarious compartments occupies the space over the spout E; consequentlyany desired fractional part of the whole into which the frame C isdivided may be taken from the bulk of the grain dropped into the hopperwhile rotating.

The hopper H is placed upon a vertical rod, b-that is, passing throughthe center of the fra-me O downward-and is pivoted upon the frame A. Thehopper is of the form of a funnel, to which a spout7 n, is attached in aposition to discharge the grain continuously into the compartments, andis rotated by means of a pulley, d, on the lower part of the rod b.

Having thus described my invention, I claim- The rotating hopper H,spout u, rod b, and pulley d, in combination with the stationary frameO, arranged substantially as and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this23d day of September, 1879.
